A very important factor in promoting the rapid development of TFT-LCD is that it has the following main application features: (1) The use of good features: low voltage applications, lower driving voltage, solid use of security and reliability improvement, flat, and light, save a lot of raw materials and use space; low power consumption, Its power consumption is about one-tenth of CRT display, reflective TFT-LCD even only about 1% of CRT, save a lot of energy; TFT-LCD products also have specifications model, size serialization, variety, easy to use, maintenance, update, upgrade easily, long service life and many other characteristics.

The display range covers the range of applications from 1 inches to 40 inches and the projected large plane, is full size display terminal, display quality from the simplest monochrome character graphics to high resolution, high color fidelity, high brightness, high contrast, high response speed of various models of video display; The display way has the direct-viewing type, the projection type, the perspective type, also has the reflection type. (2) Good environmental characteristics: no radiation, no flicker, no harm to the health of users. In particular, the emergence of TFT-LCD electronic books and periodicals will bring human beings into paperless office, paperless printing era, triggering the revolution of human learning, dissemination and record-planting civilization. (3) wide range of application, from 20 ℃ to +50℃ temperature range can be normal use, through the temperature of the TFT-LCD low-temperature operating temperature can be achieved 零下80℃. Not only can be used as mobile terminal display, desktop terminal display, but also can be used as large-screen projection TV, is a good performance of the full size video display terminal. (4) high degree of automation of manufacturing technology and good characteristics of large-scale industrialized production. TFT-LCD Industry technology mature, large-scale production of finished product rate reached 90. (5) TFT-LCD is easy to integrate and replace, it is a perfect combination of large-scale semiconductor integrated circuit technology and light source technology, and has great potential for further development. At present, there are amorphous, polycrystalline and monocrystalline silicon TFT-LCD, there will be other materials in the future TFT, both glass substrate and plastic base plate.
